WALTER JOHN AUGUSTIN, OF FONI) DU LAC, WISCONSIN.

BRAKE-OPERATING MEANS FOR PHONOGRAPHS.

Specification of Letters Patent.

Patented Aug. 2d, 18915.

Application filed September 16, 1914. Serial No. 861,977.

To all whom, it mag con cern Be it known that I, WALTER J. AUGUSTIN,

a citizen of the United States, and airesident' of the city of Fond du Lac, county of Fond du Lac, and State of Wisconsin, have 1nvented certain new and useful Improvements in Brake-Operating Means for Phonographs, of which the following is a specification.

My invention relates to phonographs, and more specifically to mechanism for actuating the brake member of a phonograph.

The object of my invention is the production of a mechanism of the character mentioned through the medium of which the brake member of a phonograph may be readily and easily actuated so as to effect stopping of the sound-reproducing mechanism of the phonograph immediately upon the completion ofthe rendition of a record.

A further object is the production of a device as mentioned which w-i-l-l-be of simple construction and eficient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in.

which,

Figure 1 is a top plan view ofa fragment of a conventional phonograph equipped with mechanism embodying my invention, and Fig. 2 is an enlarged section taken on line w;v of Fig. 1. v

The preferred form of construction as illustrated in the drawing is applied to a phonograph of conventional. construction comprising as shown a casing 1 wherein is mounted the actuating mechanism of the machine, a rotatable record support 2 being provided at the upper side of the casing 1 for supporting the record 3.

A starting lever 4 is shown through the medium of which the sound-reproducing mechanism is released for operation, as will be understood by those skillediin the art.

Arranged adjacentthe starting lever 4 is the brake member 5 whereby. thesound-re producing mechanism is 'brou ht to a stop after the rendition of a recor The brake member, in the operation of the machine, at the present time, is automatically actuated by means. of an arm 6. which is fixed to an oscillatory post 7, the latter being directly connected with the sound box or stylus of the machine so. that as the sound box or stylus traverses the record, the free end of the arm 6 is gradually moved toward the member 5, contacting therewith so as to cause stopping of the machine when the nee-- dle of the sound box or stylus has reached a position in'which the same engages in the innermost convolution of the groove of the record.

All records are not of the same length, so

that in the case of a short record or one which does not occupy the inner portion of v the groove or say the last ten or twelve convolutions thereof, the sound-reproducingvv mechanism continues to operate for a con-,

siderable time until the arm 6 contacts with the member 5 which does not occur until the needle reaches the innermost convolu of this disagreeable sound after the completion of a record that this invention is designed. With this object in view, an attachment is employed for connection with the actuating arm 6. *This attachment com- 7 prises a screw 8 in threadedconnection with a boss 9 termed at the upper side of a band or strap 10 which embraces said arm adjacent the outer end thereof, the member '10 being clamped to said arm by means of a screw 11. The screw 8 is so positioned that one end thereof is adapted to contact with the outer end of brake member 5. Through the threaded connection of said screw with the boss 9, it is clear that the former may be'adjusted as desired to accommodate records of various lengths and in the event of the screw 8 not having been previously set,

if it is desired to immediately stop the sound-reproducing mechanism, after the rendition of a record, the screw 8 may: be

manually adjusted. in order to cause the.

While l have il ustrated and described the I my invention into effect, this is capable variation and modification without departpreferred form of eonstruction for carrying ing from the spirit, of rthe invention. zI, therefore, donot wish to be limitedto the precise details of construction set forth, but

desire to avail myself of such variations and modifications ascome within the scope of the appended claims.

Having described invention what-I claim as new and desire to secure byvLetters Patent is:

1. Thecombin'ationin a phonograph of a rotating member; a brake member for cooperation with said rotating member; an actuating member "adaptedfor automatic movement into engagement with said brake to actuatethe same, astrap embracing said actuatingmember; a screw for releasably clamping said strap to said actuating member;'. and a screw in threaded connection with said strap for engagement with said brake member, said screw being manually adjustabletoward and from said brake member, substantially as described.

2. The combination with aphonograph of a rotating member; a brake member for co operation with said rotating member ;.an actuating member adapted for automatic movement into engagement with said brake to actuate the same, a strap embracing said actuating member; a screw for releasably clamping said strap to said actuating member; a lug provided on and projecting from said strap; and a screw in threaded connection with said ug for engagement with said brake member, said screw being manually adjustable toward and from saidbrake member, substantiallyas described.

3. The combination in a vphonograph of a rotating member; a brake member forceoperation with said rotating member; an actuating member adapted. for automatic movement into engagement with said brake member to "actuate thesame, a strap having a substantiallyrectangular opening therein for snuglyembracing said actuating member; a screw connecting the ends of said WALTER JOHN.
